In practice it does not really matter provided that all the
implications of your choice have been fully considered
and that having made your decision you are consistent
in sticking to it.

adjunct to the bills of quantities, for example.

Maximum flexibility in use is therefore achieved by

acknowledging the hybrid nature of the schedule

for what it is and by treating it as an independent

form of document in its own right, capable equally of

being bound into a set of drawings or into a

specification.

The package is nearly complete. However, it requires

often better shown separately from the drawing showing

the window itself, for they may well be applicable to a

appearances are widely different. Yet to term the drawing
